Abstract
Simultaneous observations of the six transitions of SiO for 106 late-type stars were made. The SiO maser emission was detected in 83 stars. Thev=3 maser emission was detected in eight stars, and the29SiOv=0 emission in six stars. The29SiOv=0 emission is stronger and narrower than that of28SiO, suggesting that the29SiO emission is masing.
